Description Usage Arguments Details Value Author(s) Examples

Makes a circular Voronoi plot.

1	CircularVoronoi(x, y, heat, EdgeFactor = 1.1, NColours = 100)

`x`	The x coordinates of the points to plot.
`y`	The y coordinates of the points to plot.
`heat`	Numerical values that will determine the colour of each tile plotted (i.e., as a heat map).
`EdgeFactor`	The proportional extension of the edge of the plotting circle (i.e., the default of 1.1 adds 10% to the diameter of the point cloud).
`NColours`	The number of (possible) colours to use in plotting (default is 100).

Intended for visualising two-dimensional projections of hyperdimensional point clouds that approximate a hypersphere. Is effectively a circular extension of the Voronoi function in the deldir package.

A circular Voronoi plot with tiles coloured according to heat values.

# Create some random data:
N <- 100
Radius <- runif(n = N, min = 0, max = 2)
Angle <- sample(1:360, size = N, replace = TRUE)
x <- Radius * cos(Angle * (pi / 180))
y <- Radius * sin(Angle * (pi / 180))
heat <- sort(runif(n = N))

# Create treespace tile plot:
CircularVoronoi(x, y, heat, EdgeFactor = 1.05)
